Answer:
y=-7; x=3
Step-by-step explanation:
You can substitute equation 2 into equation 1:
4(y+4)-2y=2
Then solve
4y+16-2y=2
2y+16=2
2y=-14
y=-7
x=-7+4
x=-3
The answer would be 1/2 in fraction form or 0.5 in decimal
Answer:

Step-by-step explanation:
The mean is the sum of the allowances divided by the number of students.

Answer:
The parent sine graph
has a range of -1 ≤ y ≤ 1
It crosses the x-axis x = 0° ± 180°n
The maximum points occur when x = 90° ± 360°n and y = 1
The minimum points occur when x = 270° ± 360°n and y = -1
The sketch the graph of function
we simply move the graph of
up 2 units.
So this means it will have a range of 1 ≤ y ≤ 3
It no longer crosses the x-axis.
The maximum points occur when x = 90° ± 360°n and y = 3
The minimum points occur when x = 270° ± 360°n and y = 1
